Not super strongly but it does stick. Spraying with oil, like wooden forms, helps make it not stick. Roughing up the surface of the foam makes it stick better. My son did an experiment with plastering/parging down the side of the pink foam on the outside of our tiny cottage in one spot. That concrete is on tight. Made me wonder about doing the whole thing but we did not have time as the cold weather was setting in. I might have a photo of what he did. I'll look around. Unfortunately it is now covered with other materials. The concrete does stick to pink board insulation. Not super strongly but it does stick.
